Reggie Jackson became Mr. October as a Yankee. He went into the Hall of Fame as a Yankee. He made more money as a Yankee.

But . . .

“I probably accomplished more here because we won three World Series championships and five pennants,” Jackson said Saturday night at the Coliseum during the 40-year anniversary celebration of Oakland’s 1974 championship team.

Jackson, who threw out a ceremonial first pitch along with fellow World Series MVPs of that era (Rollie Fingers and Gene Tenace), was among 17 players representing the ’74 champs.

He played more years with the A’s than Yankees (10 to five), hit more homers (269 to 144) and won more World Series (three to two).

The better team?

“We were pretty dang good back there then,” Jackson said of the Yankees, for whom he has been a long-standing employee. “If I had to say who would it be, I’d probably say the A’s. I thought we were very well balanced. I thought we had better pitching. We were so good because we played together throughout the minor leagues.”

At one time, Jackson was at odds with the A’s front office, and his 1993 Hall of Fame induction as a Yankee was the right move in his mind. Over time, as A’s executives changed, Jackson made peace with the organization, and his A’s number (9) was retired in 2004.

“I just bought a Reggie Jackson shirt. I think I paid 11, 12 thousand dollars for it, from 1974,” he said. “I got another one from ’71. So I’m buying my shirts back. The Oakland ones are special.”

Jackson said he’d like to see the A’s build a ballpark at Jack London Square and added, “If (the A’s) stay healthy, they’ll get their doctorate and win a championship. They got enough pitching.”
